Content and Form
The evaluation of any object of art is based on its content and form.
It is our appraisal of each by which we assigns an aesthetic value.
Content is about “Why” a piece is made.
It is about the intellectual process.
The commutative value of its meaning by the use of subject matter, narrative, metaphors, symbolism, etc,.
Form is about “How” a piece is made.
It is about the physical process.
The characteristics by which the object is made, not only the materials and techniques from which it is created but the elements of art and principles of design applied to it.

The Principles of Design
Variety / tension
Rhythm / pattern
